A microfacet BSDF for the back-scattering properties of cloth-like materials. This node is generally layered vertically over a base BSDF using a MtlX Layer VOP. All energy that is not reflected will be transmitted to the base layer.
Weight for this BSDF’s contribution, range 0.0 to 1.0. Defaults to 1.0.
Sheen reflectivity. Defaults to (1.0, 1.0, 1.0).
Surface roughness, range 0.0 to 1.0. Defaults to 0.3.
